Backlighting wheat bulb holders

[Fooman]

Good Morning all.
Just wondering if anyone knew where I could access some wheat bulb holders, the ones used to backlight the old acrylic bezels on panels. These are mounted in the aluminium panel. I have a number that are broken.
Thanks in advance,
Rob.

Tried them already. No luck.
